I don't think there will be a season 2. If there is they would have to replace the cast. Li Yi Tong is already in the 6 dramas that will be coming out in the next few years and Qu Chu Xiao has become very famous due to a movie that came out in the start of the year. They are both very busy.
For those people who have been waiting for a sequel I don't think it will happen. Mike has been cast in a show in the US. He said on his instagram that he's wanted to do acting in US since he was a child.
Buqi's Mother was RAPED RAPED !!! yet no one has a problem with it and blaming her for it. (including the commenters on Viki.) WTF she was sexually assaulted and got pregnant with Buqi and people have no problem with it ?
